As far as getting better, I don't believe there is a magic trick. It all boils down to posture and taking appropriate breaks. There have been several discussions on HN about keyboards and desks [http://searchyc.com/keyboard] but it takes a while to find a keyboard that suits you well. I personally have gone through several keyboards and have come to the conclusion that I will have to spend the money to get a really good one.

The other issue, as I mentioned earlier, is taking breaks. Getting up from your desk at regular intervals is good both for your arms, and back as well as your eyes. There are a variety of exercises you can perform while at your desk [http://tinyurl.com/rttqm].

I haven't used any speech recognition software, so I am afraid I can't help you there. In all honesty though, catching this early and doing something about it helps.

Good luck and I wish you well.
